Quadratic function question<br>​
svp [43]

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.

Hope it helps!

The area of a playground is 12 square yards. The length of the playground is 3 times longer than its width. Find the length and
marishachu [46]

Answer:

Width is 2 and Length is 6

Step-by-step explanation:

  1. As the data is given, the area of a playground is 12 square yards.
  2. The length of the playground is 3 times longer than its width.  
  3. Let width is x, length is 3 times therefore, length = 3x

As we know the formula for area,

  • Area=length x width.

So by putting values in this formula,

  • 12sq = (3x)(x)  

=> 3x2 = 12

=> x2 = 12/3,

=> x2 = 4 ,

by taking square root we get x= 2,

  • the width is 2 and length is 3 times hence, length is 3(2) = 6.

Given f(x) = x2 - 10x + 22, what is the domain of f
Lesechka [4]
<h2><u>Answer:</u></h2><h2>Polynomials have the domain of all Reals.   Plugging any Real number into the equation will give you a value. </h2><h2>Domain = {x|x∈R}</h2><h2><u></u></h2><h2><u> Step-by-step explanation:</u></h2><h2>The range is dependent on the curve itself.  The axis of symmetry for this function is</h2><h2>x = -b/2a = -1(-10)/2(1) = 10/2 = 5 </h2><h2>The vertex is F(5) = (5)2 + (-10)(5) + 21 = 21 -50 + 21 = -8</h2><h2>Since the leading coefficient is positive, the parabola opens up and the vertex (5,-8) is a local minimum.  It turns out to be an absolute minimum too so the Range = {x|x∈R, x≥-8}</h2>
